light bulb sleeve or power outlet sleeve that turns appliance on via smart phone
Internet of Things device that anyone can use right out the box, just needs a bit of plastic, relay and transmitter/receiver and a free app for your phone – just a Bluetooth relay that connects or disconnects the circuit when controlled from phone – turn your lights or appliances on or off or even set them to stick to a schedule while you are away. Easy!
You have to buy the bulb for this one, rather than just the sleeve that works with any bulb.
